Hello,

How to find ruby's help document?
for example, I want to know what's the difference between two
functions of "p" and "print", but don't know where to search.

Thanks.

These are described in the Pickaxe book which is distributed with Ruby.
Also you can use ri.

and here the standard library docs http://ruby-doc.org/stdlib/

Thanks all.
So, is there a convenient way to check the usage of a function?
like unix's `man printf` or Perl's perldoc -f print

Regards.
